Patent DE-4024657-A1 (DE)
Inventor: BAUER VOLKER DR
IPC: C11D11/00
Filed: 1990-08-03
Abstract: The invention concerns a method of converting aqueous surfactant mixtures, in particular aqueous pastes of surfactants with washing properties such as fatty-alcohol sulphates, in particular tallow alcohol sulphates and/or C12-C18 fatty-alcohol sulphates, monosalts of sulphonic fatty-acid methyl esters and their di-salts, alkylglusoside compounds, etc., into concentrated granular material with a long shelf life by granulation. The aqueous surfactant mixture, which includes as a viscosity-control agent alkoxylates of mono- and/or polyhydric alcohols with 8-40 carbon atoms which have up to 20 ethylene oxide and/or propylene oxide groups, is granulated together with fine-particulate water-soluble and/or water-insoluble solids compatible with washing and/or cleaning agents to give a free-running compound. At least part of the water content of the granular material thus produced is preferably then removed by drying, in particular in a fluidized bed.

Title: Equipment to prepare cops for automatic winder - has automatic devices to remove yarn reserve
Inventor: INOUE KAZUYUKI
IPC: B65H67/08
Filed: 1990-08-24
Abstract: Equipment to prepare fine spun cops, leaving a spinning frame by a conveyor system, with an intermediate gate before loading on to an automatic winding machine, removes the yarn reserve by suction, draws forward the wound end, severs the reserve, then tucks the end to be utilised by the winder into the top of the cop tube. The cops (1) are placed on a pinned tray (T) and transported along the conveyor (21). On reaching the gate system (22), the tray is halted and revolved by a base drive (24) to locate the end of the reserve yarn (Y1), which is drawn by suction into the wide gap of the vertical tube (26). A slot along the top arm (27) retains the yarn as the cop is advanced by the conveyor to a second gate, where it is held under the scissor device (28). ADVANTAGE - The circular conveyor is replaced by a gate, which is less complicated.

Patent DE-4143016-A1 (DE)
Inventor: BAUER VOLKER DR
IPC: C11D17/06
Filed: 1991-12-24
Abstract: The description relates to a pourable granulate, the main constituent of which are bleach activators for washing textiles in the form of a finely dispersed solid phase embedded in a virtually waterless phase penetrating the granulate grain and acting as a binder, said phase being essentially composed of solid matters. This binder phase consists of a homogenised mixture of anionic tensides and solubility enhancers in mutually adjusted proportions such that, at the working temperature for granulate formation, the binder mixing phase becomes liquid or plastic even without the addition of water. The bleach activator granulates may be obtained by premixing the finely divided bleach activators with the components of the binder and with other additives if required, homogenising the mixture of substances, preferably at moderately raised temperatures, to form a compressible mass and extruding it under high pressure into a strand, cutting the strand to the required grain form and rounding it if necessary.
